Yup, just was looking for this thread to post. Did 25 minutes on the stationary bike today, which I was amused to find out a few years ago is referred to as "spinning" by healthclubs. I had seen all these ads for "spinning" classes, and said to someone "Well, I have balance issues already, so if I spin around I tend to fall over." I got a very strange look, and then the person realized I didn't know that a "spinning class" was just a bunch of people doing stationary bikes together. Heck, even I, uncoordinated as I am, don't need a "class" to use a stationery bike!
